libsquashfs: get rid of potentially unaligned access and VLAs

2021-06-25T15:37:56+00:00

The same problem with the meta data header again, 16 bit read from a buffer: copy the buffer data into a 16 bit variable instead of casting to something potentially unaligned. Signed-off-by: David Oberhollenzer

libcommon: remove potentially un-aligned access in LZO compressor

2021-06-25T15:37:56+00:00

When accessing the 16 bit header, don't cast the buffer pointer to an uint16_t pointer, the result might not be aligned propperly. Instead memcpy to and from an uint16_t. Signed-off-by: David Oberhollenzer

libfstree: guard against link count and inode number overflow

2021-06-25T15:37:56+00:00

If the hard link counter or the inode number counter overflow the maximum representable value (for SquashFS 16 bit and 32 bit respecitively), abort with an error message. Signed-off-by: David Oberhollenzer

Fix: libsquashfs: add sqfs_free() function

2021-06-07T12:35:40+00:00

On systems like Windows, the dynamic library and applications can easily end up being linked against different runtime libraries, so applications cannot be expected to be able to free() any malloc'd pointer that the library returns. This commit adds an sqfs_free function so the application can pass pointers back to the library to call the correct free() implementation. Signed-off-by: David Oberhollenzer

libsquashfs: fix: also preserve alignment flag in block processor

2021-06-07T12:32:23+00:00

Currently, when the block processor aggreagtes fragments into a fragment block, it applies the "don't compress" flag if any of the original framgnets has it set, but the "align to device block" flag is lost. This commit ensures that both flags get applied to the fragment block if set. Signed-off-by: David Oberhollenzer

libsquashfs: fix block alignment if requested

2021-06-07T12:30:29+00:00

1) If the block alignment flag is set, the padding bytes must be inserted _before_ recording the start position, otherwise the resulting image is not readable. 2) Also perform alignment if the flag is set on a fragment block. Signed-off-by: David Oberhollenzer

added shared read access when opening sqfs image with read-only flags (win32)

libcommon: backport block processor API update

2021-01-19T10:04:33+00:00

The changes from commit 5191a25b92f903bcc2142be7ea1bfbe5ea1f5096 are backported here in a separate commit since master had some restructuring of libcommon.a after version 1.0.2 and the commit cannot be rebased directly. Signed-off-by: David Oberhollenzer
